Abstract
A circuit for heating a battery includes the battery including parasitic damping and current storage components, a switch unit, a switching control component coupled to the switch unit, a charge storage component, and a current limiting circuit. The damping component, current storage component, switch unit, and charge storage component are connected. The switching control component is configured to turn on and off the switch unit so as to control a first current flowing from the battery to the first charge storage component and a second current flowing from the first charge storage component to the battery. The current limiting circuit is configured to limit the second current flowing from the charge storage component to the battery. The circuit for heating the battery is configured to heat the battery by at least discharging and charging the battery.
